Abstract

Semiconductor component with monolithically integrated electronic circuits and monolithically integrated sensor/acutator, whereby the sensor/actuator is manufactured with methods of surface micromachining in a sensor layer (3) of polysilicon that is structured, for example, with sensor webs (6), and these sensor webs (6) are thermally insulated from a silicon substrate (1) by a cavity (4) that is produced in a sacrificial layer (2) and is closed gas-tight toward the outside with a closure layer (5).
